MANUFACTURE OF LUBRlCATlNG-JOURNALS.

SPECIFICATION forming part of Letters Patent No. 361,318, dated April 19, 1887.

Application filed August 14, 1886. Serial No. 211,767. (No model.)

To aZZ whom, it may concern:-

Be it known that I, GHARLEs PARMENTIER, asubject of the King of Belgium, and residing at Louvain, Belgium, have invented a new and useful Improvement in the Manufacture ofLubricating-Journals, of which the following is a specification.

This invention relates to lubricating-journals principally for car-axles; and it consists in aprocess for forming the same of forged iron or steel in place of cast ironor steel,,as heretofore used. The advantages thereby gained are less weight, smooth surface, greater strength, and freedom from flaws.

The journals are formed in two parts-the lower journal and a cover for the same.

Referring to the accompanying drawings, showing the lower part of said journal in various stages of manufacture, Figures 1,3, and 5 are elevations representing, as they come from the molds, the three plates of which the lower part of the journal is formed; Figs. 2,

v 4, and 6, side views of Figs. 1, 3, and 5, re-

spectively Fig. 7, section on line Q, R, and Fig. 8, section online S T, of Fig. 9,which shows the plates A in a further stage of manufacture; Fig. 10, a section on line K L M N, Fig. 14; Fig. 1 1, asection on line G H, Figs. 12 and 14; Fig. 12, a section on line 0 P, Fig. 14; Fig. 13, a section on line E F, Figs. 12 and 14; Fig. 14, a plan of lower journal completed; Figs. 15 and 17, opposite end views, and Fig.- 16 an elevation of the same. I

The lower part of the journal is made from three plates of iron or steel, A, B, and O,which are forged or stamped'in molds separately by a steam-hammer, hydraulic press, or other suitable'means, so as to give them, respectively, the forms shown in Figs. 1, 3, and 5. The first plate,'A, is provided during its stamping with the mass of steel or iron G, which is afterward bored, as shown inFig. 13, to form an inlet for the grease or oil. The plate A is also provided by the stamping or forging with two portions, h, of greater thickness, raisedtoa sufficient height to form a groove for holding the spring; The plate A is next gradually bent in several successive operations in asuitably-formed holder or matrix, which gives it the form represented by Figs. 7 to 11. The end pieces, B and 0, Figs. 3 to 6, are now forged over the edges a b c d o1- the curved plate A, Fig. 7, and the piece G bored. The lower part of thejournal is now finished and has the form shown in Figs. 14 to 17.

The corresponding cover to this journal is CHARLES PARMENTIER.
